I have been suffering from severe neck and head pain. It is at the base of my skull and INTENSE! It woke me up?

@ 6 in the morning 4 days ago. Lasted all day. Was fine when I woke up the next day, then all day just fine. Go to bed and decide to have "a little fun" with my husband and right before climax like a bad eighties band WHAM! I actually cried. Couldn't get comfortable all night long then it lasted all day the next day. Got it to subside about an hour or 2 before bed and like an idiot decided to have some fun again. Same thing. Lasted half the night. Today I am sitting on my couch and out of nowhere the same pain. Instantly in tears. I go to look it up and find some things but not enough to really calm me down any. I am 28 and have an 8 month old I am still nursing. No trauma. The only thing different I have been doing is gargling with salt water for a bad tooth. I have no insurance and little money. This is not something I can just start going and getting tests done for. I have three kids and little income. Scared to death because I suffer from migraines regularly. THIS IS NOT a normal migraine. In fact everything about it is different. It is intolerable. I would really appreciate any answers anyone could give me. Thank you, Duchess
